OK, I found a few minutes to look at the videos, although not enough minutes to digest the whole details.
Yes, bad connections cause what you say. Now, the quest is how much is this item, and what is the availability?
I sent an RFI to them, the vids would be interesting to show my students, and would be a good CEU topic, as would be a sample of the device.
To you I say 'Thanks for the info' & stay safe & healthy!!

..... The heating caused by the flow of electricity ....
Gee, I wondered how my toaster worked!
What we have is some guy deliberately mucking things up, taking pretty pictures, mixing scare tactics into his speach ... then saying 'buy my product.'
It seems like only yesterday the 'vast majority' of fires, we were told, were due to arcing connections- so we needed to start using a newly invented gizmo to solve the problem.
I'm not buying it. Plus, after the whole AFCI bait & switch, I'm not about to let a slaes campaign suddenly sneak itself into the code .... even if it's 'for the children.' Call me jaded.
Do bad things happen? Of course they do. We already have 'rules' that address workmanship, and 'standards' that address reasonable design criteria. Deliberately making something fail does not prove that the 'something' was faulty.
If a rule is being violated, we fix that violation by enforcing the rule- not by adding another rule or gadget to the mix.

I totally agree with you. In my opinion, ground fault fonction and overcurrent fonction work well, since a long time. The both = GFCI. It detects contacts between phase and ground and possibly between neutral and ground and phase-neutral.(in wiring, J-box or appliances). What more with an AFCI ? I dont know. And in this video, no arc. I imagine that rule was intentionally violated to generate a glowing connection, because GC apper often after month or years. I think video highlights that "glowing connections" are undetectable, even if the rules are NOT VIOLATED.

I don't claim to be an engineer, or scientist, or profess to have a firm grip on the 'insides' of an AFCI. When there is a 'bad connection' that generates heat, which further deteriorates said 'bad' connection, is there not an 'arc' (series arc)?? Is it less than the threshold of the AFCI cbs?
As I said above, I have seen 'burned' wirenuts over the years, and did attribute that to workmanship, be it a 'bad' splice..or a combo of a bad splice and a circuit loaded to the max.
BTW, this new item is still being developed, and is not on the market yet. Think about the elusive AFCI device!!

Hello again HotLine1
"When there is a 'bad connection' that generates heat, which further deteriorates said 'bad' connection, is there not an 'arc' (series arc)??" Not necessarily, and often not.
Arcs often reach at the end of heating (often much later). Also I tested AFCIs, and never trip with series arc! Someone tried this test?
Thank you.

Lets continue this discussion please,
The 'new' AFCI cbs are supposed to detect both series and parallel arcs? I have a few videos from Siemens that show both series and parallel arcs. The last NEC change mandated the 'combo' AFCI.
